/* ============================================================
   LIVE CHAT WIDGET  —  public/assets/chat.css
   Loaded by app/Views/partials/chat_widget.php, and ONLY when
   setting('chat_enabled') is on, so a site with chat off never
   downloads it.

   THIS IS A NEW FILE ON PURPOSE. palace.css, pages.css and
   myvan.js are byte-identical copies of the original static
   site and must stay that way, so nothing here belongs in them.

   COLOUR: every value below is either one of the design's own
   custom properties (--pl-brand, --pl-ink, --pl-line, …, all
   declared in palace.css :root) or plain white/black alpha.
   No new brand colour is invented, so re-theming the site
   re-themes the widget. The one exception is the unread dot,
   which is a fixed alert red because "you have a reply" must
   not be brand-coloured — it would disappear into the launcher.

   Z-INDEX: 1040, deliberately the same layer as palace.css's
   .scroll-top and BELOW Bootstrap's modal (1055) and offcanvas
   (1045). A chat bubble floating over an open modal is a bug.
   The launcher also sits ABOVE .scroll-top's slot (bottom:24px)
   rather than on top of it, so the two never overlap.

   MPDI REBRAND (2026-09, Chul): every border-radius in this file was
   removed — zero radius is brand law (assets/mpdi.css). Because this
   sheet is linked from the partial in <body>, AFTER mpdi.css, mpdi.css
   addresses the launcher/panel as .mv-chat .mv-chat__* to outrank it.
